    This thread will be used to capture the location of the backlight fuses for MacBook Pro LED backlit models (2008 to present). These fuses commonly open when exposed to liquid or if the LVDS connector is disconnected with power still on the logic board. I will add these as time permits. If you want to add yourself then just post in this thread and I will move the picture up to the first post to make it easy to find.

    For discussion of backlight fuse issues please use the thread on the topic at the following location.

    It's not especially hard to do it by hand with a regular soldering iron (hardest part is removing it). Of course a hot air rework or reflow oven would be a different story. Hot tweezers might be easier but I've heard they are gimmicky.

    It'd be easier to use De-solder tweezers. However, soldering back in will be a problem.

    Dadioh Help me please

    Dadioh, I honestly don't know if you still receive emails or notifications from this thread but I'm going to give it a shot. I have a Mid-2009 Macbook Pro 2.26Ghz that the backlight is out on, I shorted something I believe because I had the battery in and when I was connecting the cable to the lcd a spark flew out from the gold lock where you push it down to secure the cable in place. I don't know if the fuse is blow, or the WLED chip itself needs to be replaced. I was wondering if you would be able to do it for me? I could ship you my MacBook Pro and you could fix it? I can pay you, however I was thinking something a bit more reasonable because I am a college student and don't have $150 to shell out on a single repair. I'd appreciate a response back or any help at all, please re-direct me to the correct thread if I posted in the wrong one. I just want your reply because I saw you helped others with the backlight issue but you didn't respond back. Thank you!

So I'm looking for repair light of my screen, I've replace screen with working panel screen from other macbook because I have 2 macbook 17 A 1297. (both have failed one work but after few time it crash maybe graphic chip because panic with error on graphic).

    And where order fuse chip ?

    Thank you MacDaddi for posting the picture of the 2009 15 inch Apple Mac Book Pro A1286 logic board and location of the LCD display backlight fuse. I am hoping that some one on the MacRumor list may know this answer. I have external video through the mini display port connected to my sisters external LCD display, but I do not have video through the Mac Pro's internal LCD display.

    I bought this Mac Book Pro used on Ebay, it had been dropped with a bent corner, and bent clam shell lid and LCD display. I found a good clam shell and display locally for a reasonable price and connected the LCD display cable to the logic board with out mounting the hinges to see if it would power on, and got video for a few seconds before I accidentally disconnected the LCD display cable while powered on. I mounted and screwed in the display hinges, and reconnected the LCD display, and again tried powering it on, but had no internal display. I watched Louis Rossmonn's you tube video's several times, and Ifixit's website so I would know how to take this Mac Book apart, and put it back together again.

    I am thinking that it's the fuse, but what puzzles me is if the fuse is bad would that still allow the external display to work? If not then more then likely it's a bad internal LCD display, or the LCD display cable.

    I've been unemployed six years from my past job as a Systems Administrator in Information Technology, and do not do component level repair, so money is tight. Thank you for the help in advance, it is very much appreciated.

    Does anyone have picture of the location of the late 2008 - early 2009 unibody Macbook pro 15" Backlight fuse?

    here is the fuse. You can get it from digikey.com part #P15118CT-ND. buy a couple incase you loose one they are tiny.
    This is the backlight fuse. There are other fuses on the board but you did not specify which one.
    the description is BOARD MOUNT 3A 32VDC 0603 The "0603" is the package size of the fuse.
    --- Post Merged, Feb 24, 2016 ---
    You either shorted the fuse or burnt the pins on the lcd connector. A bad fuse would allow it to work through an external monitor. Do a continuity test on the fuse. also inspect the lcd connector if there are any burn marks on the cable connector then you will have to replace the cable. If it has burnt pins and you replace the fuse and plug in the screen it will blow the fuse again.
    Good luck!

    Here it is on the A1260/A1226, it's on the left IO board (820-2273) for some reason, it is a 603 package fuse, 32v, 2 amps.

    I know this is an ancient thread, but I'm putting this here so people don't have to spend as much time as me looking for this, since this thread was one of the first google results.

    Another broken backlight here, I attached a picture with what I think is the correct fuse for the backlight, could someone verify? Late model 2011 macbook pro 13" A1278.

    I damaged the male lcd screen connector when swapping out a broken wifi antenna. I hope it blew the fuse and it's not the female connector on the logic board itself which is bad.

    Thanks, Christof.
